The health care provider has changed a client's prescription from the PO to the IV route of administration. The nurse should anticipate which change in the pharmacokinetic properties of the medication?
- A. The client will experience increased tolerance to the drug's effects and may need a higher dose.
- B. The onset of action of the drug will occur more rapidly, resulting in a more rapid effect.
- C. The medication will be more highly protein-bound, increasing the duration of action.
- D. The therapeutic index will be increased, placing the client at greater risk for toxicity.
Correct Answer: B
Rationale: When changing the route of administration from PO to IV, the absorption process is bypassed, leading to a more rapid onset of action of the medication and consequently a quicker effect. Choices A, C, and D are incorrect. Increased drug tolerance and higher doses are not typical outcomes of changing the route of administration. Protein binding does not increase with a change to IV administration; rather, it is the bioavailability and onset of action that are affected. Moreover, an increased therapeutic index reduces the risk of drug toxicity, contrary to what is stated in choice D.

The nurse is developing a plan of care for a client scheduled for an above-the-knee leg amputation. Which action should the nurse include in the plan of care when addressing the psychosocial needs of the client?
- A. Explain to the client that open grieving is abnormal.
- B. Encourage the client to express feelings about body changes.
- C. Advise the client to seek psychological treatment after surgery.
- D. Discourage sharing with others who have had similar experiences.
Correct Answer: B
Rationale: Surgical incisions or the loss of a body part can alter a client's body image. The onset of problems coping with these changes may occur during the immediate or extended postoperative stage. Nursing interventions primarily involve providing psychological support. The nurse should encourage the client to express how he or she feels about these postoperative changes that will affect his or her life. Option 1 is an incorrect statement because open grieving is normal. Option 3 indicates disapproval, and in option 4, the nurse is giving advice.
The nurse is preparing to administer 10 mL of liquid potassium chloride through a feeding tube, followed by 10 mL of liquid acetaminophen. Which action should the nurse include in this procedure?
- A. Dilute each of the medications with sterile water prior to administration.
- B. Mix the medications in one syringe before opening the feeding tube.
- C. Administer water between the doses of the two liquid medications.
- D. Withdraw any fluid from the tube before instilling each medication.
Correct Answer: C
Rationale: Water should be instilled into the feeding tube between administering the two medications to maintain the patency of the feeding tube and ensure that the total dose of medication enters the stomach and does not remain in the tube. These liquid medications do not need to be diluted when administered via a feeding tube. Mixing the medications in one syringe can lead to interactions or alterations in the medications' properties. Withdrawing any fluid from the tube before instilling each medication can cause inaccurate dosing and incomplete administration. Therefore, the correct action is to administer water between the doses of the two liquid medications to ensure proper delivery and avoid any complications.
A client on the psychiatric unit begins to pace and continuously wring hands, and the nurse notes the client's voice is becoming louder and angrier. Which action does the nurse take?
- A. Utilize an organized team to place the client in seclusion.
- B. Allow time in the client's private assigned room for reflection.
- C. Redirect the client to a quiet activity such as journaling.
- D. Assist the client to express feelings of anger and frustration.
Correct Answer: D
Rationale: Assisting the client to express feelings helps de-escalate agitation by addressing the underlying emotions, promoting safety and therapeutic communication. Seclusion is a last resort, reflection may not address acute agitation, and journaling may not be feasible in this state.
The nurse is teaching an obese client, newly diagnosed with arteriosclerosis, about reducing the risk of a heart attack or stroke. Which health promotion brochure is most important for the nurse to provide to this client?
- A. Monitoring Your Blood Pressure at Home
- B. Smoking Cessation as a Lifelong Commitment
- C. Decreasing Cholesterol Levels Through Diet
- D. Stress Management for a Healthier You
Correct Answer: C
Rationale: The most important health promotion brochure to provide to an obese client newly diagnosed with arteriosclerosis is one focused on decreasing cholesterol levels through diet. Arteriosclerosis is significantly influenced by excess dietary fat, especially saturated fat and cholesterol. Monitoring blood pressure at home, while important, does not directly address the underlying cause of arteriosclerosis. Smoking cessation and stress management are crucial for overall cardiovascular health, but lowering cholesterol through diet takes precedence in this scenario.
